FRED M. OEDER, OF FLINT, MICHIGAN PUMP Application led August 14, 1929. `Serial No. 385,724.

This invention relates to pumps for pumping water and liquids of various kinds.

The prime object of' the invention is to provide a'pump in which the conventional` 3 pump rods are eliminated, and in which all working parts areabove the ground level, making it unnecessary to remove the entire pump for replacement or repair of the moving parts thereof.

Another object is to provide a pump o' simple and substantial design in which the deliveryspout can be in any desired loca tion, with relation to the casing.

A further object is to provide a` pump which can be placed at any suitable water level and which will deliver a volume of water equal to the area of the casing between the end of the expansion plug and the end of the discharge pipe, making unnecessary the placing' of a restricted cylinder in the casing where the water level is below the vacuum line and which accordingly limits the pump capacity. l

A further object is to design a pump with which a large volume can be secured from a small casing, which will operate effi" ciently with a limitedsupply; which is economical to manufacture and assembled, easy to install, and of rigid construction.

A further object still is to provide means for seating the expansion plug" to produce a leak-proof joint after it has been lowered to position inthe casing. y

Vith the above and other objects in view, the present invention consists in the combi. nat-ion and arrangement or partsl hereinafter more fully described, illustrated in the accompanying' drawing and particularly pointed out in the appended claim, it being' understood that changes may be made in the form, size, proportion, and minor details of construction without departing from the spirit or sacrificing any of thevadvantages of the invention.

In the drawing.

Fig. 1 is a view showing my improved pump. A

Fig. 2 `is an enlarged fragmentary sectional view thereof.

Fig. Sis a in Fig. 2.

Fig. 1 is an inverted end of said-plug.

Referring` now particularly to the drawing, the lnumeral 5 indicates a stationary plunger which can be located in any convenient desired position` above the ground level, an air cylinder 6V is reciprocatingly mounted onthis plunger, the lower end beingfopen and a rod 7 is pivotally connected to the upper end thereof. A vertically disposed legorstandard 8 isprovided direct-V ly adjacent the cylinder and one end of a handle 9 is pivotally connected thereto at the point intermediate its length, this is howeverall of the conventional type and can be variedlto suit a manual or power actuated installation.

A pipe line-11 is connected to the lower` end of the air plunger 5 leading downward plan viewol the plugl shown plan ofthe opposite lly into a conventional casing 12, the lower end of said casing projecting into the water supply. 'Y An expansion plug 13 secured in this casing at a point fintermediate its length, said plug being of smaller diameter than'the inside diameter of the casing, the lower endV being shouldered.- and threaded as shown at 111, and a. packing member 15 is mounted thereon, and is held in position by means of a tubular shoe 16, which is interiorly threaded to engage the threaded shouldered end of the pluOf. Resilient fingers 17 are riveted or otherwise suitably secured to the inner surface of the shoe, these 'lingers 'being bowed as shown, so that when the plug' is in position, these linge 's will frictionally engage the walls of the casing to hold and resist rotation of the shoe.

Spacedapart'passages 1S and 19 are provided in the plug as'shown. the` upper end ot' the passage 18 being threaded and is adapted to receive the threaded end of the pipe line 11 which connects with the air cylinder, the'opposite endV being arcuate shaped so that the area of the-passage will be uniform throng-hout. The oppositepassage 19 is identicalV in shape, excepting that the lower end "is round and threaded to receive one .end of a `discharge pipe 20, the upper end of the passage being also arcuate shaped as clearly shown in Fig. l ol' the drawiiw.

The discharge pipe 2O projects downwardly into the casing, a check valve 2l being provided on the lower end thereof, a similar check valve Q2 being provided in the end of the casing so ythat as the water is drawn into the casing, and part-icularlyv when the supply limited, that it will be trapped therein, also in certain installations, and where conditions warrant, a cheek (not shown) can he used, this is however immaterial as it forms no part ot the present invention. discharge itting 23 is provided on the upper end of the casing and through which the water is discharged, and a cap (not shown) covers the top of the casing and is provided with an opening therein to accommodate the air line.

ln assembling the expansion plug 13 is lowered into the easing on the pipe line ll, and when the desired depth is reached, the pipe ll is turned, screwing the plug against the iliaclring, expanding it in the casing, and making a tight joint that the plug will hc f. rigidly held in position, to remove the plug from the casing, the operation is merely reversed.

In practice the operation ol' the pump is as follows. 'Vhen the pump handle is in position as shown in Fig. l of the drawing, the cylinder is at the end of its downward stroke, this cylinder is now raised hv forcing the handle upwardly, as shown in dotted lines in Fig. l of the drawing creating a suction so that the check valve 2l is closed and valve 2:2 is opened, this suction draws water into the casing below the expansion plug, the volume being lgoverned by the area ot the air cylinder. .Reverse movement of the handle forces air through the pipe line ll and into thc lasing belowthe plug. closes check valve 22 and opens the valve 2l, forcing the liquid through the discharge pipe 2() into the casing above the plug, and thence out through pipe Q3, 'continued actuation of the handle repeats the operai-imi ahove desi ibed t is of course the prime object. to provide a large volume troni a small casing, and in order to accomplish this result one end of the passages i8 and 1 9 must he arcuate shaped and disposed in opposite directions, as it would be impossible (in a small casing), to secure suiiicient ster 'tor siinilar round openon one end, and such necessaryv to accommodate the air line and the discharge pipe.

ln the accompanying drawing l. have shown an air cylinder and a plunger with a handle connected thereto for manual operation, hut it will be clearly obvious that any other suitahle mechanism, either manual or power actuated may he employed.

Fre-m the foregoing description it will he obvious that have perfected a very simple,

eilicient, and economical pump for elevating liquids of various kinds.

lVh at I claim is A liquid pump comprising a casing, having a check valve on the lower end thereof, a plug mounted in said casing and having a shouldered threaded end, a packing mounted thereon, an interiorly threaded tubular shoe havino threaded engagement with said threaded end for expanding said packing t form a leali-proof joint with the casing, resilient fingers secured to said shoe and frictionally engaging the casing passages in the plug, one end of each passage being threaded and adapted to receive an air line and a discharge pipe respectively, the opposite ends being arcuate shaped, said discharge pipe projecting downwardlyv into the casing and having a check valve in the lower end thereof, and means for alternatelyv Creating a suction and pressure in the casing helow the plug, for sucking water into the lower end of the casing and exhausting` water troni the upper end thereof.

ln testimony whereof l hereunto aftx my si gnature.
